STEP-LADDER.

SPECIFICATION forming part of Letters Patent No. 466,096, dated December29, 1891.

Application filed February 26, 1891. Serial No. 382,924. (No model.)

To all whom it may concern.-

Be 1t known that I, NEHEMIAH GOLDBERG,

a citizen of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulImprovement in Step-Ladders, which improvement is fully set forth in thefollowing specification and accompanying drawings.

My invention consists of astep-ladder having the steps and side piecesconnected without the employment of nails, screws, brackets, or similarother fastenings, especially those of a metallic nature.

It also consists in providing the stay with the novel means for engagingthe supportinglegs with the ladder.

Figure 1 represents a perspective view of a step-ladder embodying myinvention. Figs. 2, 3, 4,'and 5 represent perspective views of detachedportions thereof on enlarged scales. Fig. 6 represents a top or planview of a portion of the stay and keeper thereof.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates the ladder proper, the samebeing formed of the steps B and side pieces 0. Pivoted to the top of theladder are the supporting-legs D, on which is hung the brace or stay E,the free end of which enters a keeper F, which is secured to one of thesteps of the ladder A,said stay being provided with a bent spring G,opposite to which is a shoulder H, it being noticed that when the legs Dare separated from the ladder in order to sustain the same the spring Grides over and presses against the contiguous side of the keeper, thusforcing the shoulder H into locking engagement with the opposite side ofthe keeper, and thereby connecting the ladder and legs and preventingclosing of the same. In order to release the stay from the keeper itsfree end is pressed in the direction toward the spring G until the"shoulder H clears the engaging wall of the keeper, when the stay is freeto slide in the keeper and the leg may be closed or fold against theladder, as usual in such cases. In order to strengthen the stay aroundthe shoulder H, apiece J, of metal or other suitable material, isconnected with the stay and formed with a shoulder K, registering withthe shoulder H. Y

The steps B are attached, by dovetailed or other locking joints L, toblocks M, and the latter are shouldered on their ends, so as to befitted between the side pieces of the ladder, it being noticed that saidside pieces are in pairs and formed with openings to receive dowels orother ins N, which project laterally from said blocks, it thus beingseen that the blocks are secured to and sustained by the side pieces,and the steps are secured to and sustained by said blocks, by whichprovision the steps are firmly retained in position without theemployment of screws, nails, brackets, or similar fastenings.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. A ladder having a step attached by a locking joint to end blocks, andthe side pieces of the ladder connected with said blocks by pinsentering said pieces and blocks, whereby the step is sustained withoutbeing nailed, screwed, 850., to the side pieces, substantially asdescribed.

2. A shouldered block fitted between side pieces of a ladder and pinnedthereto,in combination with a step connected by a lockingjoint with saidblock forming an improvement in step-ladders, substantially asdescribed.

3. A step-ladder havinga hinged or pivoted stay provided with a springon one side thereof and a shoulder on the opposite side, a shoulderedpiece of material connected to the stay adjacent to the shoulder andspring thereof, and a keeper secured to one of the steps with which saidshoulder is held engaged by the action of said spring, said parts beingcombined substantially as described.

4. A step-ladder having a stay hung on its supporting-leg and providedwith a spring and a locking-shoulder, a keeper secured to one of thesaid steps, and a re-enforce piece for said stay, said parts beingcombined substantially as described.
